Background technique

It has developed a variety of methods and has carried out conditioning hair.It is a kind of provide conditioning beneficial effect common method be by using Conditioner, such as cationic surfactant and polymer, hard fat compounds of group, low melting point oil, silicone compounds, And their mixture.These known most of conditioners provide various conditioning beneficial effects.

For example, the U.S. Patent Application Publication No. 2003/0103923 from SAN-EI KAGAKU is related to the group comprising alcohol Object is closed, the composition is for being blended in hair treating agent, and in the hair conditioner as made from hair treating agent.SAN-EI is public Cloth discloses a variety of such compositions for being blended in hair treating agent comprising living comprising fatty alcohol and cationic surface The composition of property agent, for example, in embodiment 100 to 110.SAN-EI announce also disclose by using it is such for blending The hair conditioner of composition, for example, in embodiment 112 to 118.

In the embodiment 112 to 117 that SAN-EI is announced, composition (102,103,104 and of embodiment of blending will be used for 106) 80 DEG C or higher are heated to, is then mainly mixed with water to prepare hair conditioner.Wherein used for blending Composition (embodiment 102,103,104 and 106) includes the fluent material of high percentage (for example, 27% the third in embodiment 102 43% glycerol in 47% Albolene, embodiment 104 in glycol, embodiment 103 and 18% Albolene, And 28% glycerol of embodiment 106) together with fatty alcohol and cationic surfactant.

SAN-EI announce embodiment 118 in, by be used for be blended composition (embodiment 111) be added to be cooled to it is low In 40 DEG C of lotion, wherein lotion has water and the compositions of additives comprising cationic surfactant and fatty alcohol, And it is in addition mixed with water to prepare hair conditioner.Composition (embodiment 111) for blending includes ethyl alcohol, cation form Face activating agent and water more than 80%, and do not include fatty alcohol.

SAN-EI announcement also discloses the preparation of hair conditioner in embodiment 150 to 156.In embodiment 150 to 154 In, the composition (embodiment 123,126,127,130,133 and 134) for being used to be blended is heated above 80 DEG C, and add Into water, which is also heated to higher than 80 DEG C, and is emulsified and cooled down to prepare hair conditioner.Composition for blending (embodiment 123,126,127,130,133 and 134) include cationic surfactant and fatty alcohol, and also comprising 15% to 20% liquid oil (in embodiment 123,130 and 133) or 6% to 8% polyoxyethylene ester are (in embodiment 126,127 and In 134).

Another example can be the U.S. Patent Application Publication No. 2003/223952 from P&G, be related to being used to prepare clear The method of cleansing composition, this method comprises: (a) be enough to allow surfactant be assigned in fatty alcohol at a temperature of will be fatty Pure and mild surfactant combines in pre-composition；(b) that mixture is cooled to the chain melt temperature lower than pre-composition is solidifying to be formed Glue network；(c) gel network is added in detersive surfactant and aqueous carrier to form cleaning compositions.The P&G is public Cloth discloses embodiment into [0190] in section [0186], coagulates using comprising fatty alcohol and the such of cationic surfactant Glue network.

In addition, the U.S. Patent Application Publication No. 2016/143827 from Kao disclose at room temperature for solid and its Middle water content is 10 weight % or smaller composition, and and being dispersed in water solid composite under mild temperature The hair conditioner composition of preparation.European patent application published number 2394632 from Shiseido is disclosed with extremely low The hair conditioner composition of water content, and thus hair conditioner composition easily can simply be made and being diluted with water It makes.

It remains desirable, however, that conditioning composition is to provide at least one of the following:

The greater flexibility of product mix rheological, especially storage modulus (G'), preferably even when use phase When the active material of same amount such as surfactant and hard fat compounds of group.It is believed that there is different rheologys, especially It is that the product composition of storage modulus (G') provides different stacking degree, and the product composition with higher stacking degree tends to Conditioning perception abundant/feel and also tend to be easy to be administered to hair and/or be easily held in palm is provided.

The improved stability of aqueous base composition and product composition, especially when by less amount of active material When such as surfactant and hard fat compounds of group are in aqueous base composition.

The improved deposition of beneficial agent when in the composition including beneficial agent；

When the stability improved comprising incompatible group of timesharing；
